September 22, 1926, Serial No. 137,136, and in Great Eritain September 29, 1825.

T his invention relates to machines for measuring,` pieces of leather and marking characters on the pieces of leather to record certain characteristics such as their thickness or length dimensions.

As heretofore constructed leather measuring and marking mechanisms have been built to be operated invariably as a unit, the measuring and marking means operating to perform their functionsas integral parts of an organized measuring and marking` machine. The combined measuring and marking machine While usually eiticient for thepurposes intended does not always meet the exacting requirements of the industry since there are at times distinct advantages in operating the measuring means as a separate unit for certain measuring operations upon leather and other similar classes of work.` On the other hand, the employment of independent measuring and marking machines, as an outlit for measuring pieces of'leather and marking the measurements oneach piece, requires a double handling of the work involving greatly increased costs due to the time and labor consumed.

It is an object of the invention to provide an improved measuring` and marking machine capable of operating as a unit upon successive pieces of work, which may be readily separated into independent measuring and markingunits of which the former may be employed for measuring operations only while the latter may be readily attached successively to any number of measuring machines in such a Way as to be operated in timed relation with each measuring,` machine thereby addingvery considerably to the etiiciency of both the marking and measuring mechanisms as compared with that of individually operated marking and measuringl machines and at the same time economizing' in the number of marking mechanisms necessary for a `n 'iven output of Work.

To these ends, and in accordance with important features of the invention, there is provided a movable support for a marking mechanism together with a stop for limiting' approaefhing movement of the marking' mechanism with respect to a measuringmechanism to protect gear; means for detacha-bly connectmg driving means for the marking mechanism with driving means for a meas uring mechanism. In the illustrated organ- 1zat1on movement of the support is controlled by guides or aligning means to carry the marking mechanism along a predetermined path toward the measuring mechanism to cause the two driving means to become operatively interconnected, thereby providing a simple construction i''or driving the mechanisms of the combined machine in timed relation. As illustrated, a controlling wheel in .the marking,` mechanism is provided with driving' connections for meshing directly with a gear on the power shaft of the measuring mechanism upon movement of the support, whereby the marking mechanism is driven from the measuring mechanism.

Another feature oi importance relates to the provision, in an organization in which the marking mechanism controlled by the operator independently of the measuring mechanism, of means by which at the termination of a marking operation certain elements of the measuring' mechanism are automatically restored to initial position, thus promptly conditioning the measuringl mechanism for operation upon a succeeding piece of work. This is a distinct advantage since without this arrangement the said elements would have to be returned to initial position through a chain of operating,r parts controlled directly by the operator, who is freed from the necessity of attendingto `this operation when operatingv the improved construction. As illustrated, this means comprises connections betvveen a controlling cam on the marking mechanism and a trip member for certain indicating and measuring elements of the measuring mechanism whereby the measuring elements are returned to initial position for a. succeedingr operation and the indicating elements to Zero position for proper operation by the measuring elements iu a succeeding measuring operation. Conveniently, and as shown, the said connections comprise an abutment on the trip member of the measuring;` mechanisn'i whereby the latter is operated by the cont-rolling cam of the marking mech- Ation will now be described in detail and pointed out in the appended claims.

In the drawing, Figure 1 is an end elevation-of a marking Amechanism and of a measuring mechanism organizedV according to the present invention;

Figi. 5 is, a detail view of the markingvmec einem.,

v In the preferred embodiment of` the invention illustrated in the drawings, marking meehanismindcated generally by X is-mounted on a support consisting of a carriage 1 comprising end frames 2 connected by tie members 2, 2b and 2c, each end frame 2 being provided withla-nged wheels 5 to run on rails 6. extending rearwards from the back of a measuring mechanism, indicated generally by Zone end frame 3 of which is representedin Fig. 1. The rails constitute means for aligning the marking and measuring mechanisms during their relative approaching movement. A portion of said frame 3 is also shown in Fig. 4. The carriage l is movable along said rails 6, i. e., towards the measuring mechanism by hand, i.e., simply by pushing or pulling, to connectr the marking mechanism detachably to themeasuring mechanism, and in the reverse, direction to cause disconnection from the measuring mechanism.

Upon reference to Fig. 1 of the drawings it will be observed that the area measuring mechanism, with whichv` the marking or stamping mechanism is designed to be detachably connected, comprises a bed roll' A which is power operated to feed hides. skins or other leather pieces beneath a plurality of measuring wheels, one of which is shown at B provided with pins C. While only three pins are shown, it is to be understood that each wheel B is provided throughout its peripheryy with equally spaced pins C which are movable by a piece of work passing. over the bed roll4 A. into position to rotate the shaftD. Rotationl of thev shaft D causes rotation of a worm wheelE 4through a worm F secured., to the shaft D and arranged to mesh withthe teeth of the Worm wheel E. Upon rotationof. the worm wheel E, a flexible member G is caused to wind .upon the hub H of theworm wheel E, the arrangement being such. that the amount of winding. of the liexible element G controls correspondinglymovements of a totalizing mechanism, not

shown, connections from which serve to operate a pointer I of a well-known type of recording mechanism, the dial of which is indicated at 73 in Fig. 2. In order that both the pointer I on shaft K and the worm Wheels E of the measuring and totalizing mechanismy may be returned to initial position after the completion of a measuring operation on one piece of work, provision is made for moving the worm F awaygfrom the worm wheel E which is thus permitted to return to initial position, this operation also restoring the pointer to its initial position on the dial'. In order that the worm F may be moved away from the worm wheel E, the upper end of the shaft D (and of all the similar shafts D) is mounted in a bar L supported at its ends in the end frames 3 for swinging movement toward and from the worm wheel E. For causing this movement of the bar L there is provided at each of its ends a short rack M in mesh withwhich is a pinion N on a shaftr O adapted toy be rocked by a lever arm 29ilv on the shaft, as will be hereinafter described. Upon upward movement of the lever arm 29a, the bar L'will be caused to swing away from the worm wheel E, thereby removing the worm F from contact with the worm wheel E, permitting this wheel and all its fellows to return to initial position, through the aetion of a weighted member (not shown) which tends constantly to return the measuring elements to their initial positions of rest. Movement of the bar L to its initial position will cause meshing of the worm F with the worm wheel E, thus restoring the parts to operative driving condition. For a more complete disclosure of the-described area measuring mechanism, reference should be had to United States Letters Patent No. 1,046,655, granted December l0, 1912, upon application of G. A. Schettler.

The position ofthe carriage l in relation to the measuring mechanism Z may be determined by adjustable set screws 8 (Figs. l and 4) tapped into the end frames 2 and adapted to abutagainst the corresponding end frames 3 of'the measuring mechanism. The carriage l may be locked in position `for use by means' of suitablevpins, bolts or other devices inserted into aligned holes in adjacent partsof the carriage andthe measuring mechanism or in lugs attached thereto. Conveniently plates 9 formed with lugs havingholes therethrough are attached to the end frames 3 of the measuring mechanismZ so as to project therefrom and are engaged by pinsor bolts l()ZL passed through corresponding holes in the end frames 2 for locating and locking the carriage l in operati-ve position. rIhe pins or bolts may have ay slight taper fitting into the holes. These pins and bolts together with the rails 6 provide means for securing exact alignment of the marking and measuring mechanisms and particularly of the operating or driving means presently to be described.

For putting the stamping or marking mechanism X in operation, there is provided a treadle comprising arms 11 tast on a shaft 12 and connectedby a bar 13 which serves as the tread portion of the treadle, said shaft being adapted to rock in the end frames 2.

This treadle actuates through intermediate .connections a clutch 14 (Fig.V 3) associated i shaft 15 and is provided with a notch into which a roller 17a, secured to a clutch lever 2B, drops at the end of each revolution of the shaft 15, the high portion ot the cam 17 serving to keep the clutch lever 23 in clutch operating position for one complete revolution of the shaft. As soon as the roller 17L drops into the notch in cam wheel 17 the lever 23 is moved to clutch releasing position by a spring 24. The treadle actuated connections to operate the clutch 14 conveniently comprise an arm 18 fast on one end of the rock shaft 12, a link 19, fitted with a counterweight 20, connecting said arm 18 with a bell crank lever 21 fulcrumed on a bearing 22 lixed on the end frame 2 adjacent to the control wheel 16. The clutch fork oryoke 23 (Figs. 1 and 3) also fulcrumed upon said bearing 22 is arranged for movement in one direction by the bell crank lever 21 and in the other direction by the spring 24. y

The control wheel 16 comprises a toothed gear 16a (Fig. 1) which, when the carriage 1 is moved up to the measuring mechanism Z, meshes with an appropriate gear wheel 25 rotatably mounted on one end frame 3 ot the measuring mechanism and driven by a pinion 26 on main shaft 26a of said measuring mechanism. That is to say when the carriage 1 is operated to move stamping unit X into operative relation to the measuring lunit Z a driving connection between it and the measuring unit is made automatically. The adjustable eet screws 8 serve as stop devices to limit the relative approaching movement of the two mechanisms to protect the intermeshing gears 162325. y

To enable the measuring and indicating devices ot the measuringl mechanism to be automatically released and returned to zero when the stamping means are actuated, there is provided a lever 27, Figs. 1 and 3, fulcrumed on a pin 28 in the end trame 2 adjacent to the control wheel 16 so as to project from the carriage support 1 ot the marking mechanism and, when the latter is moved up to the measuring machine, to engage means for controlling the measuring and indicating devices. In the illustrated construction, the measuring mechanism Z is equipped with lever arms 29, 29n (Fig. 1) connected by a counterweighted link 30, the arrangement being such that the lever 27 engages a pin 31 on the link 30 and is operated to lift the latter for restoring thc measuring devices to Zero. This operation may be accomplished by depressing a treadle (not shown) connected to the shaft 29" when the measuring mechanism is used separately.

r1`he lever 27 is actuated at the proper time by a cam 32 (Figs. 1 and 3) lined on the sha lt 15, said lever being fitted with a roll 33 for engagement by the cam. Upon operation ot the lever 27 by the cam .f 2, the link 30 is li ftcd thus moving the lever arm 29 upwardly. This movement of the arm 29"L causes disconnection oi" the worms F from the worin wheels lll by reason ot which the wheels lil and the totalizing mechanism operated thereby are all permit-ted t9 return to intial position. Hence the lever 27 in co-operation with the link and abutment or pin 31 may be considered to be the means for causing, or tor initiating, restoration of the measuring elements to their initial rest positions. tince the pointer is operated from the totalizing mechanism by direct connections it too permitted to return to initial position, in tiis case, through the action of gravity on certain parts ot the totalizing mechanism as described in detail in Patent No. 1,046,655 already referred to. From the foregoing description it is clear that the operator initiates return of the `measurin elements by depressing treadle 13.

The carriage 1 carries a stamping mecha nism of the type described in applicants copending application Serial No. 135,009, filed Sept. 13, 1926.

Referring to Figures 1 and the type setting means shown therein comprise slidable plungers 1, 1 and 1b, and resp ctively corresponding levers 102, 102iL and 102b freely mounted on a carrier shat't 103 rotatably supported in end frames 4 in which the main portion of the stamping mechanism (hereinafter described) is mounted. The plunger-s are jointed by pin-andslot connections to the levers the depending arms of which latter constitute stops or abutments for engagement selectively by a series oi projecting pins 105 disposed in the form oli a spiral or volute in the usual manner in corresponding sprocket disks 106, around which type cle ments 7 on flexible carriers 10Ta are passed and which are frictionally and rotatably driven while supported on a shaft 108. The shaft is driven first in the direction of the arrow (Fig. 1) to bring the yieldingly driven disks 106 into set positions as determined by pins 105 in contact with the dcliending arms ot the levers 102, 102", 102". Subsequently Elf.)

the shaft 108 is rotated in the opposite direction to return the disks 106 to initial position. Upon reference to Fig. 5 it will be observed that the disks 106 are tightly pressed toward each other, and against Washers (one of which is shown at 106b) keyed to the shaft 108, by means of springs 106@ Each disk is thus frictionally driven and may .be stopped independently of the others by a lever arm acting on one of the pins 105. For a more complete disclosure of the driving means for the type disks reference may be had to United States Letters Patent No. 1,173,312 granted Feb. 29, 1916, upon application of G. A. Schettler. In the present arrangement each of the levers 102, 1023, 102b has upon it a weighted arm 109 so that when required it can be turned to bring the free end of its depending arm into position to act on the appropriate pin 105 in the adjacent disk 106. The turning movement of each lever 102, 102, 1021 is controlled by its associated plunger 1, 1, 1", avhich is operated by the corresponding cam section 10 of a stepped disk 10 arranged to turn with the indicator pointer I of a measuring machine r. an)

with which the marking mechanism is associated. For a more complete disclosure of the construction and mode of operation of the cam disk 10c, reference may be had to United States Letters Patent No..1,111l.,917, granted Oct. 27, 1914, to G. A. Schettler.

Since the aforesaid levers 102, 102", 102 are freelymounted on the shaft 103 for movement to operative position, means are provided for holding said levers and their associated plungers 1, la, 1", in the normal inoperative position, for freeingl them for movement to operative position, and for restoring them to initial position. To this end the boss of each lever 102, 10221, 102b may have circumferential notches or Oaps 111 formed in one end of the boss for engagement by a pin 112 fixed radially in the shaft 103 which latter is rotatable in the direction of the arrow (Figure 1) to free the levers so that they can be turned by their weighted arms 109 until arrested by the plungers 1, 1f, 1b, the shaft 103 being rotatable in thev reverse direction to restore the levers 102, 10221, 102D, to and hold them in inoperative or initial position. The notches or gaps 111 in the lever bosses are made long enough to allow the levers 102, 102, 102b sufficient free movement to take up the various positions determined by the plungers 1, 1a, 1.

It will be understood that each of the disks 106 is arrested by the contact of one of its pins 105 with the free end of its associated lever 102, 102e, or 1021, and that such disks, when arrested, bring the required types into position for subsequent printing or marking of the measurement upon the material. In this connection, it is to be understood that the disk 10C with its cam sections 10 moves with the pointer shaft K of the indicator 73 mounted on the frame of the combined marking and measuring machine, and that the greater the movement of the disk 10c the greater will be the movement of the disks 106 to bring the higher-numbered type into place to stamp the appropriate characters on the work. In order that the various types, i. e. those of the different elements which correspond, for instance, to the units and tens columns, may be properly aligned, provision is made for adjusting the levers 102, 1023, 102b on the carrier shaft 103 so that the position of arrest of any disk 106 can be moved forward or backward as may be required. To this end each lever instead of being mounted directly on the shaft 103, is mounted upon an eccentric bushing 113 (Fig. 1) which is free to turn on the shaft. The lever is fastened to the bushing by a set screw (not shown) or other suitable means, and the bushing has a knurled flange (not shown) to enable it to be turned by hand in the lever after slackening the set screw. The said bushings are made shorter than the lever bosses so as to avoid the radial pins 112 but if desired the bushings may be made as long as the bosses and have corresponding notches or gaps formed therein to accommodate said pins. A further lever 102C (Figure 5) formed without a depending arm' but mounted and operated in a manner similar to the other levers 102, 1022, 102b is provided on the shaft 103 and connected with it is a plunger 1C fitted with a pawl 114 for engagement with teeth 10a on the periphery of the stepped disk 10C, when the levers are freed by rotation of the shaft 103 as pre- `viously described, to lock said disk in the type selecting position. The aforesaid plungers 1, 1a, 1b, may be slidably supported by a bearing 116 (Fig. 1) mounted on a cross member 117 connecting the end frames 4, and the pawl may be pivotally carried' by an arm 118 extending from the said bearing.

The carrier shaft 103 may be operated by a cam or 4other means. Conveniently, said shaft has an arm 119 (Figs. 1 and 5) fast thereon and connected by means of a link 120 to a bell crank lever 121 which is fulcrumed at 121a on one of the end frames 4 and fitted with a cam roll 122 for actuation at the required time by a cam 123 (Fig. 5) on the main shaft 15 of the stamping mechanism, the weight of the parts with the assistance of a spring (not shown) serving to keep the roller 122 on the cam 123 on shaft 15. ln this way the cam 123 operated in properly timed relation serves to permit the levers 102, 102a and 102b to move to position to lock the type disks 106 in selected positions, and subsequently to release the disks by moving the levers back to initial position.

In this marking machine, which is especially adapted for use with a measuring machine, the controlling cam disk 10c of the com'- bined measuring and marking machine is mounted upon the shaft K which carries and operates the pointer I of the indicator means of the measuring machine. It will be recalled that in this type of indicator means the pointer comes to rest after the last measuring element of the measuring machine loses contact with the work as the rear end of the work passes from the field of measuring operations. rihe pointer of the indicator means and the pointer shaft remain locked in the indicating position of the pointer until they are released at the will of the operator. The cam disk 10c which is operated from the pointer shaft is also locked in position to control selection of appropriate type blocks by which the measurement indicated by the pointer may be stamped on the work by the type blocks. Immediately after the cam disk 10c comes to rest in its type selecting and controlling position the operator throws in the clutch 14 of the marking machine, this operation being immediately followed by a partial rotation of the shaft 103 under control of the cam 123, the shaft moving in the direction of the arrow in Fig. 1.

Rotation of the shaft in the direction indicated permits the weighted levers 109 to operate the plungers 1, 1a, 1b and their respectively connected levers 102, 102, 1021), moving the plungers toward their respective cams 10. Obviously the plungers 1 1a,

. and 1b may move to the right in Fig. 1 such distances as may be determined by the cams 10 carried by the cam disk 10C. It is to be understood that `the amount of rotation of the cani disk 10C determines the height of each cam at point opposite to the end of each plunger 1, 1a, 1b. In this way the cams 10 control the setting of the plungers and hence of their connected levers, 102, 102, 102, Immediately following the setting of the plungers and their connected levers, the type disks 10G are caused to rotate in the direction of the arrow in Fig. 1, each disk rotating until one of the pinsiO carried thereby strikes the end of its associated levers 102, 1022, 1021, which lever thus acts as a stop for setting the type disk 106 in selected position. CSince the type disks 10G are yieldingly driven from the shaft 108 the latter continues to rotate,

`making a complete revolution. thus insuring that each disk 106 will finallyv reach selected position. During t-he rotation ofthe disks 106 the type elements 7 are moved along therewith and are finally brought into selected position belowr a type wheel 150, as shown in Figs. 1 and 5 of the drawings. While the type blocks 7 are in selected position, awork support or table hereinafter described is caused to lift the work to press it against the type whereby proper characters are marked on the work.

The carriage 1 is tted `with a table 40 to receive the material to be stamped or marked as it comes from the measuring mechanism Z, and also with a mechanism whereby the material is lifted into contact with types on the type elements 7. This lifting mechanism inchicles a spring pressed bed or block 42 attached to a plunger 43 and adapted for movement between guides 44 mounted on cross members 45 and through an opening 46 in the bed or table. The cross members 45 are attached to the end frames 2 and serve `for the support of intermediate connections through which the plunger 43 is operated at the required time by a cam 47 (Figs. 1 and 3) on the control wheel shaft 15. The plunger may slide through a bracket 48 attached to the cross members 4.5 and said intermediate `connections comprise a bell crank lever 49 fulcrumed on a bracket 50 and pivotally attached to the lower end of the plunger 43, an adjustable link 51 connecting said lever 49 to a similar bell crank lever 52 fulcrumed on a bracket and a connecting link 5413etween the lever 52 and a bell crank lever 55 fulcrumed on the pin 28 and fitted with a roll for engagement by the cam 47 on the shaft 1.5.

Distance pieces furnished by tubes 21 are provided on upper tie rod 2a between the opposing frames 2 and 4 of the carriage and the stamping mechanism, and similar distance pieces 2e are placed on the remaining tie rods 2a between the frames 2.

As has heretofore been stated, the marking mechanism mounted on the movable carriage 1 may be used selectively with any one of a number of measuring mechanisms by moving it into proper alignment with the measuring mechanism and securing the two together with their driving means in interconnected relation. Furthermore it may be readily detached from its associated measuring mechanism by movement of the carriage 1 to permit the measuring means to be used alone for the single operation of measuring pieces of work. After the marking mechanism has been properly aligned with and operatively connected with a measuring mechanism in the manner already described, a piece of work passed through the combined measuring and marking machine is first measured as to its area and subsequently marked with characters in dicating the said measurement. In operating the machine, a piece of work is lirst presented to the bed roll A (Fig. 1) by which it is fed toward the table 40 of the marking mechanism passing meanwhile under the measuring wheels B which co-operate with the bed roll A in feeding the work. It is to be understood that the measuring wheels B are rotated because of their contact with the `work and hence stop their rotative movement as soon as the rear end of the Work has passed by.

During the rotation ofthe wheels B the pointer I is being gradually moved over the dial 73 and it finally stops in indicating position Vafter the last measuring wheel B has come are moving, the disk l()c with its cams l0 is also moving since the disk 10c is either secured to the shaft K or directly Operated therefrom. Hence the cams 10 are moved to a position which corresponds exactly vto the position of the pointer I. It is only after the pointer Iand the cams 10 come to rest that the marking mechanism is operated. In the illustrated construction and arrangement, operation of the marking mechanism is initiated by stepping upon the tread of the treadle 13. Hence the marking means is con-v trolled by the operator independently of the measuring elements. Depression of the treadle causes the throwing in of the clutch 14 whereupon the plungers l, la and lb are moved toward the cams 10, the extent of their movement being determined by the height of each cam opposite the end of each plunger.

The extent of movementof the plungers l,

la and l" determines also the extent of movement of the type elements 7 which are moved through means provided for that purpose to present, opposite to the bed or block 42 in the table 40, type blocks 7 with characters corresponding to the measurement indicated by the pointer on the dial 73. As soon as the selected type elements 7 have reached their proper positions, the block 42 is power operated in the manner described to press the work against the type. Subsequently the block 42 returns to its lowered position and `this is followed promptly by operation of the lever 27 which lifts the lever arm 29a to cause disconnection of the worms F from the worm wheels E, thus permitting the measuring mechanism and also the tctalizing and indicating devices all to return to initial or rest position. Since the cam members 10 on the cam disk 103 are connected to the pointer shaft K, the cams 10 are also returned to initial position and thus both the measurr, ing and marking means are conditioned for operation upon another piece of work.
